A833 O/D gears in an A833 1:1 ?

I think it has to do with the gear cut on the countershaft.
Wayne will know for sure.

Thanks for checking on the thermostat end. I think it has 10-32 threads so I might be able to put a ring terminal on it if I cannot find an end. The junkyards here crush everything if it is over 10 yrs old.
